SPECIFICATION forming part of Letters Patent No. 638,071, dated. November 28, 1899. Application filed July 26, 1898. SerialNo. 686,911. (No model.)

To all whom it may concern:

Be it known that I, CHARLES HERBER SCOTT, a subject of the Queen of Great Britain and Ireland, residing at Gloucester, in the county of Gloucester, England, have invented Improvements in Means or Apparatus for Use in the Manufacture of Inlaid Linoleum, (for which I have obtained a patent in Great Britain, No. 979, dated January 13, 1808,) of which the following is a specification.

In the manufacture of inlaid linoleum it has heretofore been common to use stencil-plates formed of plain sheet metal formed with large perforations, the shape of which depends upon that of the pattern to be produced,and through which linoleum material is forced onto a backing by correspondingly-shaped plungers. Such stencil-plates and plungers are costly to construct, and, moreover, one set of them is suitable only for producing one pattern, so that for producing several patterns a corresponding number of sets of stencil-plates and plungers are necessary.

Now this invention has for its object to obviate the foregoing disadvantages and to provide a single set of stencil-plates and pl ungers that can be readily adapted for producing an infinite variety of patterns, as I shall'nowdescribe, with reference to the accompanying illustrative drawings, wherein Figure 1 shows in vertical section a portion of a stencil-plate, with plungers, pressureblock, and adjacent parts, according to this invention. Fig. 2 is a similar view to Fig. 1, showing a modified arrangement. Figs. 3, 4, and 5 show, respectively, in side elevation, plan, and cross-section on the linexcc of Fig. 3 par-t of one construction of machine suitable for carrying out my invention. Fig. 6 is a part longitudinal section on the line y y of Fig. 5. Fig. 7 is a part plan of the stencilplate shown in Fig. 6. Fig. 8 is a part side elevation, Fig. 9 a part plan, and Fig. 10 a detail view, illustrating a modified arrangement.

According to-this invention each stencilplate 1 (see Fig. 1) is made of perforated or reticulated sheet material, the perforations in which are made of small and uniform size say of circularshape and of aboutone-eighth or three-sixteenths of an inch in diameter-and in conjunction with such a plate there are rovided a number of vertically-movable plungers 2, the diameters of which correspond to that of the holes in the plate, the said plungers being held in a correspondiugly-perforated vertically movable plate 3 and depressed at the required times by a verticallymovable pressure-block 4.

The holes in the stencil-plate 1 not required for the particular pattern to be produced may be stopped in any suitable manner, as by a sheet 1", Fig. '7, of perforated paper or other material the outline of the perforation or perforations in which corresponds or correspond to the outline of the part of the pattern to be produced by the stencil, and the corresponding set of plungers 2 are so placed in the top plate 3 as to correspond with the unstopped holes. Linoleum 5 in the form of granulated material or in the form of sheet material is placed over the stencil-plate 1 by suitable means and the plungers 2 are caused to descend and force the linoleum that is over the holes through the same onto a suitable backing 6, which is caused to move in an intermittent manner below the stencil-plate 1, these operations being repeated as often as may be necessary for the pattern being produced. In this way the backing is more or less covered with a number of small cylinders or blocks of linoleum, which are afterward pressed or rolled, and thus made to completely cover the backing. Instead of stopping the holes not required for the pattern being produced by paper or other material they may be stopped by wax or similar substance.

The holes in each stencil-plate should be made as small as practicable, so that as little as possible of the granulated-linoleum mixture 5, when such mixture is used, will fall through the. same before the descent of the plungers 2. The holes may be made so small that the material mentionedwill not fall unaided through them. In this case the holes not required for any particular pattern neednot be stopped, the plungers only being properly arranged to suit the pattern to be produced. A perforated plate 7 is or may be fitted to slide on or relatively to the plungers 2 for the purpose. of removing any linoleum mixture that may adhere between them. This plate may be fixed or becaused to descend and press lightly on the surface of the loose.

supporting-plates 3 according to the pattern to be produced, the said plungers may, as shown in Fig. 2, be so supportedas by springs 8, arranged between their heads 2 and the supporting-plate 3, through which they extend and which in this case is station arythat only those plungers whose heads are acted upon byasuitably-shaped block 9, (hereinafter called a pattern-block,) attached to the under side of the pressureblock 4, will be depressed when the pressure and pattern blocks are depressed. The pattern-blocks 9 will correspond in plan with the particular part of the pattern to be produced and may he slid into position on the bottom of the corresponding pressure-block 4. By providing a number of such pattern-blocks and inserting them successively into position to be acted upon by the respective pressureblocks patterns of considerable length and variety can be readily and cheaply produced. Such pattern-blocks may be connected and arranged to be fed forward after the manner of jacquard-cards, the action of which they more or less imitate.

As will be obvious, my invention can be used in linoleum-making machines which in other respects may be variously constructed.

In the machine shown in Figs. 3w 6, inelusive, each of the stencil-plates 1, made as thin as practicable and stiffened at the edges, as by being secured to a frame 1, (see Fig. 6,) is provided with a tiering-box 10, which is arranged to travel forward and backward over the surface of the plate and has its rear side 10 vertically adjustable in order to vary,

according to requirement, the rate of flow of linoleum mixture 5 from the box through the slit 10", and consequently the depth of the layer of such mixture deposited on the plate 1 during the forward motion of the box. The linoleum mixture may be fed by a feeding device 10 and chute 1O into each tiering-box when the same is in its rearward position. Above each stencil-plate is avertica1ly-movable pressure-block 4 and a series of plungers 2,adapted to fit the perforations in the stencil-plate 1. Below the several stencil-plates the backing 6 is caused to move in astep-bystep manner by an endless conveyer, such as that described in. the specification of another application for Letters Patent filed by me, Serial No. 686,910. Each time the backing comes to restthe tiering-box 10 of each stencilplate 1 is caused to move in one direction-say the forward direction, shown by the arrow or in Fig. 6and deposit all over the said plate alayer of linoleum mixture 5 of suitable thickness. When the box has arrived at the end of its forward movement, the corresponding pressure-block 4c is caused to descend and cause the corresponding plungers 2 to compress the linoleum mixture 5 which is over the correspondingperforationsin the stencil-plate 1 onto the backing 6 until the level of such material practically coincides with the lower surface of the stencil-plate 1, whereupon the said stencil-plate is slightly raised by suitable means, after which the pressure-block and plungers are again raised and the tiering-box returned to its starting position. In some cases the plungers may first compress the linoleum through the perforations to the level of the upper surface of the stencil-plate, then rise, after which the box is returned to its starting position, so that during the return movement of the box loose linoleum mixture on the plate will be caused to reenter the box through the slit 10 at its lower rear end and also to enter and completely fill any perforations or parts thereof in the stencil-plate 1 which may not be already filled. The pressure-block 4 and plungers 2 are then caused to again descend and further compress the material in the perforations of the stencilplate until the level of such material practically coincides with the lower surface of the said plate, whereupon the stencil-plate is slightly raised, as before, after which the pressure-block 4 and plungers 2 are again raised. The backing 6, with the compressed pieces of linoleum thereon, is in either case then moved forward a suitable distance, the stenoil-plate lowered, and the above-described operations repeated.

Each block 4, with plungers 2, Fig. 1, can be raised and lowered by any convenient means. In the example shown each block is carried by a cross-piece 4,the ends of which are arranged to work vertically in guideways in standards 11 and are carried by springs 12, which tend to raise and hold the block, with plungers, in the raised position. Each block is moved downward against the action of its springs 12 by a transverse beam 13, which is arranged below the'stationary table 4: and ismoved downward against the action of springs 14 by cams 15, arranged to be rotated by two longitudinal shafts 16 and to act against an tifriction-rollers 13 on the beam 13. The connect-ion between the blocks 4 and cross-pieces 4 and the means for depressing them may be such that any one of the blocks can be put out of action while the machine continues in motion. For this purpose each block 4, through its cross-piece 4?, may be connected to the corresponding beam 13 below it by a pair of rods 17, so that the block and beam rise and fall together, and the cams 15 are feathered to the shafts 16, so that they will rotate therewith, but are capable of being moved endwise thereon by forked levers 18, which engage grooved bosses 15 on the cams and are fixed on a rock-shaft 19, provided with a hand-lever 19, the arrangement being such that by operating the handlever in one direction or the other the pair of cams can be brought over or moved from above the beam 13, according as it is desired 1 operation.

to put the corresponding block in or out of The cams 15 are each formed with one or two projecting or operative parts, (two are shown in Fig. 5,) so that they will act to depress the pressure-block and plungers once or twice, as may be desired, for each rotation of the shafts 16, as and for the purposes hereinbefore explained. The said shafts may be driven through worm-gearing 20 from a transverse driving-shaft 21.

In the example shown the tiering-boxes 10 are moved backward and forward over their respective stencil-plates 1 by longitudinal tiering-bars 22, to which they are attached and which are caused to move to and fro on the framing A of the machine bya pair of lever-arms 23, that are connected to the said bars by links 24 and are fixed to a rock-shaft 25, which extends from one side of the machine and is rocked at the required times by suitable means, such as cams, located within a casing 26. Each tiering-box 10 is arranged to travel on the sides of the frame 1 of the corresponding stencil-plate 1, and a lateral toand-fro jigging motion may be imparted to it in the manner and for the purpose explained in my said other specification. The tieringbars 22 may be connected to any suitable arrangement of energy-accumulator that will serve to cushion them and their attached parts at each end of their strokes and by then giving out energy facilitate their movement in the reverse direction.

The Vertical movement of each stencilplate 1 may conveniently be effected at the required timesby cams 27, fixed on the shafts 16 and arranged to act upon the long arms 28 of bell-crank levers pivoted at 28", so as to raise the short arms 28 of such levers and through vertically-adj ustable screws 29 slightly raise the stencil-plate and hold the same raised until the pressure-block, with plungers, has been again raised, and the backing 6, with pieces of linoleum thereon, has been fed forward another step, when itis allowed to fall back onto the table of the machine. The extent of lift of the plate can be varied by adjusting the screws 29 vertically.

Figs. 8, 9, and 10 show means whereby any one of a number of pattern-plates 9 with pattern-blocks 9 thereon, can he slid into position beneath a pressure-block 4. In this case the several pattern-plates are supported horizontally one above the other by and between a pair of lateral supports 30, that are arranged to be moved downward between guides 31 by stepped cams 32,-acting through connecting-rods 33 and levers 34, and to be raised by the action of springs 35or their equivalent. The pattern-plates 9 are each slid endwise into a box 4*, belonging to the corresponding pressure-block at and crosspiece 4, by a pair of side bars 36, which are attached to the adjacent tiering-bars 22 and each of which is provided at its upper end With a pair of lugs 36, (see Fig. 10,) which are arranged to engage with a projection 9",

extending laterally from the lower surface of the corresponding side of each pattern-plate 9 when the same is brought into a horizontal line with them, but which will not interfere with the vertical movements of the plates.

Each pattern-plate is slid into the corresponding box 4* at a sufficient height to clear the heads 2 of the plungers 2, which are normally held in their raised positions bya spring surrounding each of them and are prevented from rising too high by a pin passing through each of them below the plate 3. The arrangement is such that when the cross-piece 4 starts descending it presses the pattern-plate down onto the heads of the plungers2before the box 4* starts descending,'the box being balanced by a spring or other suitable means.

It will be evident from the foregoing description that the thickness of the linoleum applied to the backing is regulated by the depth of the layers of linoleum mixture tiered onto the stencil-plates or the sheets of linoleum fed over the same and not by the thickness of the stencil-plates.

To make linoleum of a great-er thickness than would be made when proceedingin the manner hereinbefore described, each stencilplate, after the corresponding pressure-block 4 and plungers 2 have made their first stroke and before they are again raised, may be lifted slightly, so that when the plungers afterward rise the holes in the plate will on the return movement of the tiering-box be able to receive the further quantity of linoleum mixture necessary to produce the extra thickness of linoleum required, the additional quantity of linoleum being afterward pressed through the stencil-plate by the plungers until level with the under side thereof, as before. The said raising of the stencil-plate may be effected by cams 27 in the manner and through the means hereinbefore described, the said cams being, however, each formed with two operating parts of different eccentricity,as indicated in dotted lines, as respects the second part, so that they will act to lift the stencil-plate in two successive steps for each rotation of the shafts.
